I Found a way of cheating nested.
Take my File From Dropbox.com here: https://dl.dropboxusercontent.com/u/202751393/html.txt
find this code using the find function (normally ctrl+F)
var SeedObject="galaxy";//This can be set to anything else, like "firefighter" or "donut box".
and change the seed to what you want. my default is 'galaxy'
if you do not know the seed name just hover over it in nested and it will say 'archetype: itemname'
Finally: save it as a .html file and open it with your favorite browser.
